nAIL-nxirnaczrcn AND, HAMMER- To all whom it may concern Be it known that I, HENNING K. JOHN- .soN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and-State of Minnesota, have invented certain new and useful Improvements in NailExtractors and Hammers, of which the following is aspecification; a

This invention relates to combination tools, and more particularly to a combined nail-extractor and hammer; the primary ob ject being to provide a tool for extracting nails when opening packing-boxes and the like, which may, in additionto its utility as a nail extractor, be used as a hammer when the paclnng-box is being assembled or closed.

One of the principal objects of this invention is to provide an improved tool which will have the hammer element so constructed and associated with the nail-extractor means as to causethe' hammer element to A further object of this invention isthe provision of a nail-extractor and hammer which consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the'invention "and the advantages and merits thereof, reference is to be had to the following description and the accompanying drawings, wherein is illustrated the preferred form of my invention, in which:

Figure 1 is an elevation of the device showing it in use as a nail extractor, parts being broken away to disclose the construction Fig. 2 is an opposite side elevation showing the position the device will assume when used as a hammer; and

Fig. 3 is an end elevation.

Referring to the drawings wherein is i Specification of Letters Patent.

illustrated the preferred form of my invention and in which like characters of reference indicate corresponding parts throughout the several views, the shank 1 is provided at oneend with a handle 2 and at its opposite endwith a claw 3, A foot piece or shoe 4 is pivotally mounted on the shank 1 7 adjacent the claw 3 and this shoe consists of a relatively narrow casting having a slot 5 formed therein through which the shank 1 is extended. Reinforcing lugs 6 are formed on opposite sides of the casting to give strength to the same at the point where the V openings 7 are formed for the reception of apivot pin 8. 7

Near the slot 5, and at the end of the shoe opposite the tang 9, is an opening 11 for the .reception of the shank 12 of a complementary extracting claw 13 the point of which is disposed toward the claw 3 whereby the two claws 3 and13 may cooperate to obtain a grip on the nail, as shown to advantage by Fig. 1 of the drawing.

For the purposes of this description, the complementary claws will be designated as the mainclaw 3 and the accessory claw 13. In the proper operation of the device it is necessary to firstfirmly grip the handle and press downwardly on the main claw 3 until the point of the claw isembedded beneath the head of the nail to be extracted. The handle is then pulled toward the operator and the accessory claw 13 will move into engagementwith the head of the nail as shown by Fig. 1 of the drawing, while the tang!) acts as a fulcrum for the device whereby thenail may be removed. -It is essential that some weight be applied to the accessory claw 13 and for this purpose I have provided an arcuate extension 14: which, in addition to its use in. connection with the claw, is also used as a hammer as will be presently described. lhis extension is integrally formed with the casting constituting the shoe 1 and the portion of this extension is cored out to form the opening 15 whereby the greatest bulk of the weight is at the solid end 16 of the extension, the latter also forming the hammer head. It will be obvious that'when the device is used as above described the weighted end of the extension will assist the claw 13 in its gripping action on the head of the nail. The claw 13, of course, is fixed in proper position by a set-screw 17 Referring particularly to Fig. 2 of the by providing a certain curve in the extension 14: soythat the greater portion of the weight ofthe casting from which the shoe is formed directly over, the striking surfaces 17 when the hammer is brought into play when driving a nail. lin other words the weight is properly balanced so that the device has all the advantages of the. ordinary nail hammer in addition to. its function and.

utility as a nail extractor.

In order that the hammer portion may be 7 held rigidly when the device is used as a hammer, l have provided a locking sleeve 18 which consists of a rectangular casing mounted upon the shank 1 and freely slidable thereon. One side of the casing or sleeve has a screw-threaded opening to reccive the shank of the set-screw 19 which has a finger grip 20 whereby the set-screw.

may he easiily' manipulated. When used as a nail-extractor as shown in Fig. 1, the sleeve is ralsed and held in raised pos1t1on by the set screw 19 so that free pivotal movement of the nail-extracting means is.

permitted. When in use as. a hammer the sleeve will be moved forwardly into engage ment with the shoe as shown by Fig. 20f the drawing and held in this position by the setscrew so that the hammer portion will be rigidly held to the handle or shank to effect the proper use of the device as a hammer.

From the foregoing it will be observed that a very simple and durable nail ex-. tractor and hammer has been provided, the details of which embody the preferred form. Idesire it to be understood, however, that slight changes in the minor details 01 construction may be made without departing l romthe spirit of the invention or the scope otthe claims hereunto appended.

I claim- 1. A tool of the character described comprising a shank having a claw fixed at its end, a shoe pivotally connected to the shank 7 near thesaid claw having an arcuate tang projecting fromone end and an arouate extension projecting from the opposite end, the end or the said extension being shaped to provide a hammer head, the same being disposed considerably beyond the adjacent end of the shoe to add weight to the latter, and a complementary claw carried by the said adjacent-end oi": the shoe.

2.]A. tool of the character described comprising a shank having a claw fixed at its end, a shoe pivotally connected to the shank near the said claw and having an'arcuate tang projecting :t'rom'one end and an arenatc extension projecting from the opposite end, the end of the said {extension "being shaped to provide a hammer head, the same being disposed considerably beyond the adjacent end of the shoe to add weightto the latter, and a complementary claw carriedby the said adjacent end of the shoe, t he said tang being curved in an are opposite to the curve of the said-extension wherebythe end of the latter willbe disposed in a plane considerably above the said tang when the latter is in operative position;

In a tool of the character described, thecombination of a pair of complementary claws, a shank having one of the claws formed on its end, a shoe having the shank pivotally connected thereto adjacent the said claw, the other claw being adjustably fixed to the saidsho'e whereby pivotal movei'nent of the shoe will cause-coopera H.
